KEY MESSAGES

Issued at 1125 PM CST Sun Dec 28 2025

- Wind chills are expected to drop into the single digits across the northern combined Panhandles tonight and Monday night.

SHORT TERM

(Tonight through Tuesday night) Issued at 1125 PM CST Sun Dec 28 2025

Water vapor satellite imagery shows a potent upper-level trough is moving its way through the Midwest and into the Great Lakes region this evening. Meanwhile, a weak positively tilted trough over California and Nevada is retrograding, poised to undercut a ridge just off the West Coast.

A cold airmass will continue to settle into the Panhandles overnight, and highs in the upper-30s to 40s is expected across the area on Monday as high clouds move across the southern Texas Panhandle. Lows on Monday night will be cold but a few degrees warmer than tonight. A surface high will move off to the southeast of the Panhandles which will turn the low-level winds southwesterly, bringing in a warmer airmass. Look for highs on Tuesday to quickly rebound into the mid to upper-50s.

LONG TERM

(Wednesday through next Sunday) Issued at 1125 PM CST Sun Dec 28 2025

An upper-level trough will remain over the Great Lakes and Northeastern US to begin Wednesday, and a ridge will begin building over the Southwestern US as a trough is favored to begin to approach California. Rising heights aloft is favored for the Panhandles on Wednesday, supporting subsidence, and continued warm air advection will favor temperatures warm into the upper-50s to 60s on Wednesday.

Most operational and ensemble members support the idea that the previously mentioned trough off the West Coast will begin to move into the Southwestern US on Thursday, resulting in the development of a lee surface low along the front range of the Rockies. Most of these members have this surface low tracking southeast throughout Thursday and Thursday night, but it seems unlikely that noticeable weather changes will result other than some changes in wind direction. With that said, if a stronger surface low develops, we could see highs be slightly cooler than currently forecast (upper- 50s to upper-60s), particularly in the eastern Panhandles.

An upper-level ridge is likely to build over the Great Plains this weekend as another trough is favored to move into the West Coast. Expecting highs in the 60s for this weekend with the potential for some to get into the low-70s.
